1. A dedicated SBEC per servo can protect the rest of the servos , and the receiver in case of abnormal situation like a servos blocked because of the control surface, or an unlikely malfunction of the servos.
2. Regulating the output current and avoid the servo overloading.
3. When using Lipo 7.2~8.4V, the SBEC can provide stable voltage to the servo.
4. Linear mode; No interference.
